One problem for life insurance consumers is that - when issuing travel warnings - the US State Department lumps all of Israel together with Yesha.
However, from the perspective of endangerment to lives, some insurers are quite willing to recognize the relative risks and not paint all of Israel and Yesha with one broad brush. They can understand the difference between traveling to the West Bank and traveling inside the Green Line.
That said, affordable life insurance is available even for travelers whose destination is Yesha. The key is (1) understanding that insurers specialize in specific risk portfolios and (2) finding a broker who's done his homework and knows which carriers compete for this business.
